Bite

Melee Weapon Attack: +12 to hit, reach 10 ft., one target. Hit: 16 (2d10 + 5) piercing damage.

Breath Weapon

The dream dragon breathes out a rainbow breath in a 90-ft. cone. This creates a hallucinatory terrain in which those affected must fight and defeat the dream dragon. If anyone in the area fails a DC 19 Wisdom saving throw, all targets in the 90-ft. cone enter the dream terrain. The only way to escape the dream terrain is to slay the dream dragon. Once the dream terrain is activated, the dream dragon chooses what form it takes. The dream dragon also is able to use an action to have an element from the terrain strike out and attack one target, the target must succeed on DC 19 Dexterity saving throw or take 60 (11d10) bludgeoning damage. The hallucinatory terrain is only destroyed if the dream dragon is defeated.
